Steps to reproduce the problem:
1. Enable Auto-fill in settings.
2. Go to any website that ask for credit card information.
3. Type the information and click submit.

What is the expected behavior?

What went wrong?
After submitting, Chrome ask the user if he want to save the credit card information.

Did this work before? No 

Chrome version: 50.0.2661.94  Channel: stable
OS Version: 6.3
Flash Version: Shockwave Flash 21.0 r0

tl;dr
Allow to disable credit card auto-fill while enabling the other parts of auto-fill.

Many users regard credit card number as a highly sensitive information and therefore want credit card information has a separated settings from normal auto-fill.
